Happens ALLLLLLLL the time in Football, heck there are even twitter account parodies of specific coaches(ahem Michigan coach, Alabama coach) who are notorious for offering 150 verbals a recruiting cycle for 25-30 roster spots. As for lacrosse specific, look at what is going on at U Tampa. The earlier and more frequent early recruiting gets, you can bet your dollars on it increasing.
And FYI, Tampa not a reputable D1 program, should not even be in this conversation,
